STAMFORD — Gov. Dannel P. Malloy joined Mayor David Martin and other state and city officials and business leaders on Tuesday to discuss his transportation proposals inside the mayor’s 10th floor conference room.

During the roundtable meeting, Malloy reintroduced his plan of spending $100 billion to improve the state’s transportation system over the next 30 years, just six days after he presented the state budget. Malloy said the plan includes maintaining and upgrading the railroads, highways, bridges and bus system.

“Modernizing Metro-North (Railroad), for instance, and adding a second station in New Haven, a new station in Orange and rebuild the station in Merritt 7,” Malloy said, citing a number of Connecticut train stations slated for refurbishment or new construction.

“A lot of it has to do with getting people in and out of Stamford from other parts of Connecticut. If you think about the chance to expand the reasonable commutation, the number of people who can take or accept jobs in Fairfield County, that’s a net plus for Fairfield County,” Malloy added.

Martin said he wanted to know the timetable for implementing the governor’s plans.

Fairfield County is an economic engine for the state, Martin said, shortly after the meeting.

“I happen to believe that the Metro-North Railroad is probably the most single significant issue for the people and jobs in Fairfield County, and we need to get started on that,” Martin said. “I know he’s already started on the Walk Bridge …. They talked about modernization of (Metro-North), but I haven’t seen the detail on that.”

Juanita T. James, president and CEO of the Fairfield County’s Community Foundation, said she’s interested in seeing progress in affordable transportation for young people attending community colleges.

“For example, anybody from Stamford who has to go to Norwalk Community College, if they don’t have their own car, it’s very difficult, because if they do take the buses, the schedule is very spotty. It doesn’t really operate well in the evenings or weekends.”

James said transportation is key to retain young adults in the county.

“We’ve had a 10 percent reduction in the 16 to 24 age group over the past few years in Fairfield County because we are not providing young people with the access and skills that they need to live and work here,” James said. “And I think transportation is a big part of that.”

Bud Grebey, vice president of corporation communications, raised the issue about the city’s bus schedule mismatching the train schedules.

“If you go to New York and get a train ticket, you can also get a subway ticket at the same time in the same ticket. In Stamford, people don’t even know what the bus schedules are. That’s part of it is our own ignorance, but that’s also because nothing is being published or pushed out,” Grebey said.

DOT commissioner James P. Redeker and state Reps. William Tong and Caroline Simmons also attended the meeting.
